Gain/Exposure Priority for Snapshot Mode
Parameter # 562 (SSI # F1h 32h)
This parameter alters the digital scanner gain exposure priority when it acquires an image in Snapshot Mode in
auto exposure mode.
Scan Low Exposure Priority to set a mode in which the digital scanner favors higher gain over exposure to
capture an image. This results in an image that is less susceptible to motion blur at the expense of noise
artifacts. However, for most applications, the amount of noise is acceptable.
Scan Low Gain Priority to set a mode in which the digital scanner favors longer exposure time rather than
higher gain to capture an image. This ensures that the image is less noisy and produces fewer artifacts
during post processing activities like image enhancement (sharpening). The mode is recommended for fixed
mount / fixed object image capture since the image acquired is susceptible to motion blur.
Scan Autodetect (default) to set a mode in which the digital scanner automatically selects Gain Priority or
Low Exposure Priority mode for Snapshot Mode. If the digital scanner is in a magnetic reed switch enabled
stand (or it is configured in Blink Mode), it uses Low Gain Priority mode. Otherwise, it uses the Low Exposure
Priority mode.
